Get a culture!

Protein in urine is not treated with antibiotics, so you must have had an infection.

Call your doc back, tell him/her that you're having symptoms again, and ask for a urine culture and sensitivity. If they did a culture the first visit, they may not have done a sensitivity. If they did, then can tell if the bug might be resistant to the antibiotic you took.

Can't think of the name of the med right now....but there is one that's used as a 3 day treatment. My doc has tried that with me twice and I've had to go back on another antibiotic to get a complete cure. The last time I took the same med, but for a full 14 days and it worked the first time. It may be that you're resistant....or it could be that the treatment period wasn't long enough.

In any event, you need to call your doc. The protein is probably as a result of the infection. But you probably should have a follow up to make sure it goes away.
